Mmmmmm this is my FAVORITE sandwich to make: First slice the bell peppers into thin strips, vertically. Thinly slice the tomato while you're still wielding the knife, and then put it away! You could hurt someone! Sprinkle cajun seasoning on peppers. Cover vegan bread with mustard, put down a layer of bell pepper, making sure that the different colors are evenly distributed. Then put on some lettuce, tomato, and pineapple and maybe even some soy cheese if you want some extra yumminess. Pineapple is also VERY good on pizza with peppers, try it!
